Unfortunately, only the USA has actual regulations that allow hand inspection of photographic materials. The FAA has a sign for this, which is often (but not always) posted at airports. I don't believe any of the EU nations allow this liberty. Also, the FAA explicitly warns that one should never put photographic materials in checked baggage. There is a large technical literature about the effect of carry-on scanners, but one should remember that the dose to the film is cumulative if you need to go through checked-baggage x-ray many times before development.
